5. Check for the black or red tank gasketon the on the bottom of the Tank-in Tank® Assembly. If the gasket is lodged in the base of unit, reattach it or order a replacement (it’s the same as the SmartMix bottle, see above).

6. Check the valve on the bottom of the Tank-in-Tank to make sure water will come through when the x-valve is pressed. The bladder may be empty or the valve may be blocked internally. If no water comes out when you press the valve, you’ll need to order a new valve. You can do so here: http://www.bissell.com/parts/?sc=part&productid=22496&partid=4432

8. Check if the small rounded tabs on the floor nozzle are locked in the slots on the top of the base and not inadvertently lifting the tank up out of place.
